The author recently experienced a rare case of squamous cell carcinoma affecting the left nasal vestibule. A 38 years old male was visited to our clinic on July, 25, 1967, with chief complaints of the ulcerative changes and a punch-out defect on the left nasal vestibule for about one year duration. The biopsy confirmed as squamous cell carcinoma and good result was obtained after excision and radiation therapy.
